RESEARCH ON SEISMIC ANISOTROPY-A REVIEW

Plastic flow induces lattice preferred orientations that influence on seismic anisotropy in rock-forming minerals of crust and upper mantle. In the review of rapidly growing literature on seismic anisotropy,the accent is put on progress and achievements in the study of seismic anisotropy. The origin of anisotropy is discussed. Finally implications for seismic anisotropy in geodynamics are mentioned.
